[fusion-users] MapServer Transparent PNG Layers

[Nolte, Tim]

I'm attempting to user multiple MapServer maps using transparent PNGs so
that the end-user perception is that things load much faster. I'm
running into two problems:

1.) The 4 defined maps are not stacking correctly, getting my last map
(points.map) underneath one of the others (us_streets.map). But what is
interesting is that this behavior is not consistent, sometimes they are
in the right order but sometimes they are not.

		<MapGroup id="mapserver" xsi:type="MapType">
			<Map xsi:type="MapLayerType">
				<Type>MapServer</Type>
				<SingleTile>true</SingleTile>
				<Extension xsi:type="CustomContentType">
	
<MapFile>/export/home/www/ipcs/map/basemap.map</MapFile>
					<Options>
	
<isBaseLayer>true</isBaseLayer>
					</Options>
				</Extension>
			</Map>
			<Map xsi:type="MapLayerType">
				<Type>MapServer</Type>
				<SingleTile>true</SingleTile>
				<Extension xsi:type="CustomContentType">
	
<MapFile>/export/home/www/ipcs/map/regions.map</MapFile>
					<Options>
	
<isBaseLayer>false</isBaseLayer>
					</Options>
				</Extension>
			</Map>
			<Map xsi:type="MapLayerType">
				<Type>MapServer</Type>
				<SingleTile>true</SingleTile>
				<Extension xsi:type="CustomContentType">
	
<MapFile>/export/home/www/ipcs/map/us_streets.map</MapFile>
					<Options>
	
<isBaseLayer>false</isBaseLayer>
					</Options>
				</Extension>
			</Map>
			<Map xsi:type="MapLayerType">
				<Type>MapServer</Type>
				<SingleTile>true</SingleTile>
				<Extension xsi:type="CustomContentType">
	
<MapFile>/export/home/www/ipcs/map/points.map</MapFile>
					<Options>
	
<isBaseLayer>false</isBaseLayer>
					</Options>
				</Extension>
			</Map>
		</MapGroup>

		<MapWidget xsi:type="WidgetType">
			<Name>Map</Name>
			<Type>Map</Type>
			<StatusText>The map.</StatusText>
			<Extension xsi:type="CustomContentType">
	
<MenuContainer>MapContextMenu</MenuContainer>
			</Extension>
			<MapId>mapserver</MapId>
		</MapWidget>

2.) When I try the above map setup the Legend sort of breaks. I have to
set ShowMapFolder to 'true' in order to even get something more then
just the first group of the base layer to show up in the Legend. Also
most of the individual layers with their legend symbols show up, with
the exception of the few layers that I have condition CLASSes on. I'm
attaching 2 screen shots as examples. Does anyone have any ideas how to
fix this?

		<Widget xsi:type="WidgetType">
			<Name>Legend</Name>
			<Type>Legend</Type>
			<StatusText/>
			<Extension xsi:type="CustomContentType">
	
<HideInvisibleLayers>true</HideInvisibleLayers>
				<ShowRootFolder>false</ShowRootFolder>
				<ShowMapFolder>true</ShowMapFolder>
				<GroupInfoIcon/>
			</Extension>
		</Widget>
